Why cant i trade in my paid JOD device towards a new device?

TL;DR: If you pay the purchase option price all at once, then you have to wait 64 days from the end of the lease for it to be eligible as an upgrade. If you finance the purchase option price over 9 months, then the device is eligible as soon as the final payment is made. 

Jump! on Demand is a very interesting finance option because it has many benefits, but it also has some fine print that can get confusing. Most people like JOD because they can get a device for $0 down most of the time, the monthly payments can be a bit lower, and they can upgrade the device easily every 30 days if they want to. The fact that it is a lease is where things get a little weird. If you do get to the end of the lease and want to keep the phone, technically you have 60-64 days to decide if you want to make the lump sum payment or over the 9 months. If you do the lump sum payment, you would think that you could trade the device in right away, but there are ways for you to change your mind and reverse the payment and set up the 9 month payment plan. That buffer period is the reason for the requirement for customers to wait 64 days for the device to be eligible for trade in.
